If I were building something from scratch, I'd probably try to come up with a way to give other investors (everyone except for me) veto power over the Exodus Address funds. That is, if somebody thought I was using funds inappropriately, there could be a vote, and I would respect their wishes by trying to find an alternate way to accomplish the goal.

Votes would probably be based on investment size, although that would obviously be dominated by the mystery person who purchased 420BTC worth of MasterCoins.

Obviously, this veto power would still require people to trust me, but they are doing that anyway.

Another way would be to nominate a couple people to hold this veto power. I think Ripper and Vokain would do a fine job, given their obvious interest and investment in this project, although spiral_mind will claim they are just sock-puppet accounts which I control.

FYI, here is a list of reimbursements I intend to file immediately come September 1st:

• $80 for netbook purchase (clean OS install, used for armory offline-only transaction signing for the Exodus Address)
• Reimbursement for Ripper's purchase of MasterCoin.org (how much?)
• Reimbursement for laptop purchase for development (I'll be purchasing it this weekend in Oregon, where there is no sales tax - since I'lll be using Armory and copying armory code, I spoke to Alan Reiner and he said I should get something with a lot of RAM)
